The blower/fan for AC and heat inside the car just doesnt come on. Is this a known issue? I have a 2009 328 under warranty. The AC/heat part is working there just isn't any fan action to circulate it or push it into the car.

It was loosely jammed and I was able to get it moving with my fingers.
Sprayed WD-40 and it began rotating freely.

There's a slight rubbing / grinding noise that comes intermittently from under the glove compartment.
I checked using the second procedure and found that the ducting was loose (the metal clip had popped off). Hopefully this'll be the end of it or I'll have to go in for a new motor.

You will eventually need a new motor. The design is bad. The blower motor is oriented vertically (i.e the motor shaft poinst straight up). The blower fails because either water (from an improperly fitted cabin airfilter cover) or just plain old condesation trickles down the shaft and gets into the top bearing, which eventally wears out. If your fan has been making noise and rubs a bit, then the bearing is already shot. The replacement is really easy. The motor is about $80.

WD-40 would not be a good lubricant in this situation. You should use a lithium silicone based lubricant.

I agree though that your motor will most likely have to be replaced.

ENINTY, do you have your old blower by any chance? It would interesting if we could take a look at the bearing and see if a better one can be installed.

I had my blower replaced under my new car warranty but they never replaced the windshield cowl cover like I asked them too which is why it failed. I know it will fail again sooner or later so it would be cool if we could just buy a new bearing opposed to a whole new unit.

My blower motor is still chugging along.

It gets stuck occasionally and I have bought a new one that I haven't put in yet as I've recently begun getting water near the driver-side dead pedal, and passenger foot-well after a car wash.

All drains seem OK so I guess it's the cowl as diagnosed in other threads.
